32GB DDR5 ECC RDIMM for Lenovo servers

This 32GB DDR5 5600MHz registered DIMM is built for IBM-Lenovo systems that require ECC RDIMM modules. It suits administrators upgrading compatible ThinkSystem or ThinkAgile platforms where registered error-correcting memory is mandatory. The 2Rx8 organisation and 1.10V operation match the DDR5 server baseline. Buyers needing unbuffered UDIMMs or non-ECC memory for workstation or desktop boards cannot use this module.

Major-brand DRAM ICs and lifetime warranty

Each module uses major-brand DRAM IC chips and undergoes quality-assurance testing before shipment. The supplier provides a lifetime warranty and United-States-based technical support for the life of the product. No heat spreader is included, so airflow in the server chassis must handle thermal management. The package contains a single 32GB stick; no additional cables, software or mounting hardware are supplied.

288-pin DDR5 5600 registered ECC 2Rx8

The decisive specification is the 288-pin DDR5 RDIMM form factor running at 5600MHz (PC5-44800) with ECC, registered buffering and a 2Rx8 rank layout at CL40. Only systems that explicitly support DDR5 registered ECC DIMMs at this speed and rank configuration will accept the module. Verify the server memory-qualified-vendor list and channel population rules before purchase.

Questions about this item

Will the 2Rx8 ECC RDIMM modules need replacement after a certain number of write cycles?

DDR5 ECC RDIMM modules do not have a write-cycle limit that requires scheduled replacement; they are solid-state components rated for the lifetime of the server platform.

What thermal limit appears first when this 5600 MHz module runs at full load continuously?

The module operates at the standard 1.1 V DDR5 voltage without a heat spreader, so the DRAM junction temperature will reach its throttling threshold before the registered buffer or PCB becomes a bottleneck.

How much power does the 32 GB 2Rx8 kit draw and how loud is the cooling when the server runs all day?

At 1.1 V the module draws only a few watts and has no moving parts, so it adds negligible heat and zero acoustic noise to the chassis airflow.
